From 84876662417aab8f90d685cf6bdd9471f2353022 Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Fri, 22 Jul 2016 16:21:51 -0700 Subject: [PATCH] std: Ignore tests where threads outlive main Long ago we discovered that threads which outlive main and then exit while the rest of the program is exiting causes Windows to hang (#20704). That's what was happening in this test so let's just not run this test any more. --- src/liballoc/arc.rs | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/src/liballoc/arc.rs b/src/liballoc/arc.rs index e762e4d8ce9..64b780413f8 100644 --- a/src/liballoc/arc.rs +++ b/src/liballoc/arc.rs @@ -21,6 +21,10 @@ //! //!
